Description
The Streamlight TLR-4 is one of the smaller light-and-laser combos out there, which is the whole point. It was built for sub-compact and compact pistols where a full-size weapon light would look and feel oversized, though it also clamps onto most full-size handguns with an accessory rail. You get a 170-lumen C4 LED throwing a clean 3,300-candela beam out to about 115 meters, plus a 640-660nm red aiming laser, all in a unit that weighs just 2.81 ounces with the battery and measures 2.73 inches long.
What the TLR-4 Brings to a Pistol
The three-position mode selector is the heart of this thing. Flip it to run the white LED by itself, the red laser by itself, or both together, so you can set it up the way you like for the situation. The ambidextrous rocker switch handles momentary and steady-on, which means lefties and righties both get an easy reach without shifting their grip. The laser sits in a brass bushing with windage and elevation adjustment screws, so once you zero it, it holds that zero through recoil and daily carry.
Mounting the TLR-4 Without the Hassle
Streamlight went with a rail grip clamp instead of a slide-on bar, and it makes a real difference. You snap the light onto the side of the rail and tighten it down with one hand, so your fingers never cross the muzzle while you attach or remove it. The included key kit covers a long list of frames, from rail-equipped Glocks to the Smith & Wesson M&P, Springfield XD, Sig P-series, Beretta Px4, and plenty more.
Durability is where Streamlight usually earns its keep, and the TLR-4 fits the pattern. The body is impact-resistant engineering polymer with an anodized aluminum facecap, the C4 LED is rated for a 50,000-hour lifetime, and the whole unit carries an IPX4 water-resistance rating. It runs in temperatures from -20°F all the way up to +120°F, and the single CR2 lithium battery gives you 1.5 hours in light or combo mode and up to 15 hours on laser only. Streamlight backs it with their limited lifetime warranty.

Frequently Asked Questions
What handguns does the Streamlight TLR-4 fit?
The TLR-4 was designed with sub-compact and compact pistols in mind, but it also clamps onto most full-size handguns that have an accessory rail. The included key kit covers a wide range of frames, including rail-equipped Glocks, the Smith & Wesson M&P, Springfield XD, Sig P-series, and Beretta Px4. There are also separate versions built specifically for the H&K USP Compact and Full-Size frames.
How long does the battery last on the TLR-4?
Running the white LED by itself or the LED and laser together gives you about 1.5 hours of regulated runtime. Switch to laser-only mode and you can stretch that to roughly 15 hours. It runs on a single 3V CR2 lithium battery, which is included, and that battery has around a 10-year shelf life.
Can you use the light and laser at the same time on the TLR-4?
Yes. The three-position mode selector lets you choose the white LED alone, the red laser alone, or both running together. That flexibility is one of the main reasons people pick a combo unit like this over a light-only weapon light.
Do I need a holster made for a TLR-4-equipped pistol?
For carry, yes, you'll want a holster cut to fit your pistol with the TLR-4 mounted. A proper holster fully covers the trigger guard, which keeps things safe and secure while the light is attached. Plenty of holster makers offer models sized for popular pistols with the TLR-4 in place.
